High Energy Theory Seminar

Maximal Unitarity at Two Loops
David Kosower, CEA-Saclay

note: time change

Ā 

The unitarity method is a key part of the set of on-shell methods for calculating gauge-theory amplitudes both analytically and numerically. These methods have been used successfully to obtain the one-loop amplitudes needed for a variety of cutting-edge high-multiplicity next-to-leading order calculations for LHC physics. In this talk, I discuss how to extend the maximal unitarity method to a computation of two-loop amplitudes, needed for precision LHC calculations.
